-6 Claims.

The object of this invention is to provide an improved guide for vertically slidable sash of the type used in the Windows of railroad cars and buses.

In this improved guide the surface of the same which is engaged by the side rail of the sash is serrated in the ldirection of movement of the sash,` and the cooperating portion of the side rail is covered with a strip of pile fabric which is pressed into conformity with the serrations. This construction permits the sash to be raised and lowered easily and quietly and provides a thoroughly weatherproof closure. l

While the foregoing statements areindicative in a general way of the nature of the invention, other more specific objects and advantages will be apparent to those skilled in the art'upon a full understanding ofthe construction, arrangement and cooperation of the inter-engaging guide and sash parts.

Three different forms of the invention are presented herein for the purpose of exempliflcation, but it will of course be appreciated that the invention is susceptible of embodiment in still other structurallyv modied forms coming equally within the scope of the appended claims. In the accompanying drawing: Fig. 1 is a horizontal section through one side of a window constructed in accordance with the invention;

Fig. 2 is a fragmentary perspective view of a short section of the serrated outer stop shown in Fig. 1; 4

Fig. 3 is another horizontal section, on the order of Fig. 1, showing a modification of the invention; and

Fig. 4 is a similar sectional section, showing still another modiflcationof the invention. The' window structure which is illustrated in Figs. 1 and 2 includes a sheet metal sash I0, a post plate II, an outer stop I2, and an inner stop I3. The sash I0 slides up and down with its side rail I4 confined between the stops I2 and I3. The side rail I4 is pressed against the '45 outer stop I2 by the outwardly wedging action of the bolt I5 of the lock I6 on the sash, which bolt engages with a beveled rack formation on the inner stop I3. I

The outer stop I2 consists of a metal strip of L-shaped cross section which is attached by lscrews I1 to an abutment I8 formed on the post plate Ii. One flange I9 of the strip I2 is positioned against the abutment I8, while the other flange 2U of the strip is positioned in slightly spaced parallel relation to the post plate II in movement of the sash.

(Cl. 18S- 65) opposition to the edge of .the side rail I4. The inner face of the flange I9 is provided with a plurality of vertically extending seri-ations `2l 'for coaction with the sash, and the outer `face of the ange I9 is provided with similar serra-l 5 tions 22 for interiitting engagement with serrations 23 formed on the inner face of the abutment IU.

By removing the screws II the strip I2 can be shifted horizontally toward or away from the 10.y

edge of the sash a distance corresponding to the width of one or more of the serrations 22, whereby to obtain the desired amount of clearance with f respect to the sash 'regardlessof any departure from standard width found. in the particular 15 i the outer face of the side rail projects into conforming I.engagement with the serrated face of -the stop I2, while the pile on the portion which overlies the edge of the side rail projects to- 25 ward the limiting flange 20 of the stop, preferably in slightly spaced relation to such ange when the latter has been properly adjusted to iitfthe sash. The flange 20 acts to prevent the sash from 'working edgewise or canting in its 30 guides, but there is but little likelihood of the sash doing this due to the track-like guiding engagement of the serrations 2| in the outer stop with the resilient pile structure of the fabric strip. 'Ihe fabric strip is secured to the' side rail :i5

by having its edges tucked in behind the edges of a backing strip 26 which is in turn clamped to the side rail by screws 28.

The exposed margin of the fabric strip 24 at the edge of the stop I2 is shielded from a too 40 direct exposure to the elements by a narrow baiile 21, which baille projects outwardly from the outer face of the side rail in slightly spaced relation to the adjacent edge o f the stop I2 and is formed asa flange on a metal strip 28 which 45 embraces the edge of the side rail. 1 The serrations 2l on the outer stop I2 compact the pile into a plurality of parallel multiple-sealing furrows, providing a very satisfactory weather-tight closure.. and at the same time mak- 5o ing for easy sliding while resisting all Widthwise In the particular window structure shown in Figs. 1 and 2 the outer stop I2 and certain-of the other associated parts arealuminum extrusions, 55

but it will of course be understood thatv any other material or method of forming may optionally be employed in manufacturing these parts.

In the modification which is shown in Fig. 3 the serrated outer stop 30 is formed as an integral part of a sheet metal post plate Il In the modification which is shown in Fig. 4 an adjustable channel guide 32. on the order of the one shown in Sevison Patent No. 2,037,934 is employed. 4 The serrations 33 are formed on the stationary outer side 34 of the guide. In this guide structure the-inner side 35 of the guide, together with the back 38, Ais adiustable toward or away from the post to obtain the desired amount of widthwise clearance between the guide and the sash.

While in each of the three embodiments presented herein only one guide structure has been shown, it will of course be understood that a similar guide structure is intended to be employed at the opposite side of the sash.'

The facing material for the side rails of the sash, while preferably pile fabric of the type Y hiown as Schegel Cloth may be any other L equivalent material of Aresiliently compressible nature.

I claim: 1. In window construction, a vertically slidable sash-provided with soft resiliently compressible faoings on the outer surfaces of its side rails, and guides for the sash provided with vertically extending serrations in the plane of the outer surfaces of the side rails for embedded association with the facings. t

2. In window construction, a vertically slidable sash provided with resiliently compressible pile fabric facings on its side rails, and guides for' the sash provided with closely arranged vertically extending serrations for embedded association withl the facings.

3. In window construction, a vertically slidable sash provided with' resiliently compressible pile 'fabric facings on its side rails, and guides for the sash provided with closely arranged vertically extending serrations for embedded association with the facings, said guides being adjustable toward and away from the sash.

4. In window construction, post plates provided with vertically extending serrations in the plane of the window, sash stops-provided with corresponding serrations in interlocking association therewith, and means for releasably clamping the stops to the post plates in various positions of adjustment widthwise of the window opening.

vided 'with a plurality of closely arranged serra- Y tions in a plane at right angles to the edge of the sash for embedded association with an impressionable covering on one side f the sash.
